What I've been doing with my alu ball is this process.
1. heaping TBL in my first ball with the water at the 400 line
2. shake for 5 minutes, make you complete tap all the moisture you possibly can out of the ball
3. move on to the next tablespoon but this time after the first 5 minute shake your gonna take a butter knife, mix it around a bit and repeat.
4. Same for the next tablespoon, when your done you should be at a shell and then some worth of kava.
Best result for me but I for the life of me can't get consistent satisfying effects from day 3 and forward. I had to cut down to 2 times a week for a kava because though I feel ok I don't get what I want out of kava from day 3 and forward in a row. I have to wait for it to just about completely wear off and exit my system. Sometimes like this week for example I just won't get a very satisfying session at all. I'm sure I'm not just being hard to please because from day 3+ I'll get that liquid like sensation but not very strong and a feeling of general well being but no euphoria and my body won't be totally feeling it radiating throughout it well and my face won't have the familiar warm numb feeling when I have a real good one with the complete stillness of mind I get.
